This kit serves two purposes. In case you're worried something might go wrong- you have two chances. The main reason people chose this option is to teach sharing and reduce cost. We are careful to choose slightly different size caterpillars so they are not emerging at the same time. A Bug Keeper with two Monarch caterpillars, all the food they need and viewing instructions. It takes about two weeks until you release two Monarch Butterflies!
